Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the rates for the hadronic decays B[sup[+-]][yields][pi]K can be used to derive information on the weak phase= arg(V*[sub ub]) in a largely model-independent way. Hadronic uncertainties can be reduced to the level of nonfactorizable contributions to the decay amplitudes that are power-suppressed in[Lambda]/m[sub b] and, in addition, either violate SU(3) flavor symmetry or are doubly Cabibbo suppressed. Various strategies to obtain bounds on and to extract its value with small theoretical uncertainty are described. The potential of B[sup[+-]][yields][pi]K decays for probing physics beyond the Standard Model is also discussed.
